whiohjtlmiollowin'g description, in connection with the accompanying drawings, is a specification, like reference characters on the drawi'ngsindicating like parts in the several This inventionvrelates to machines tor shaping the heel :ends of boots and shoes. In machines for operating upon the heel ends of completed uppers for shaping them under the-influenceof pressure or heat and pressure between an inside former,-outside formersand flange-turning wiping means with a view to facilitating-subsequent lasting or 'improvingthework generally, it has be'en proposed; to advance the formers to and retract "xthem f rom the wiping means after the completion of the flange turning opera- 1 the inside former has "been directly moved and 1 the: outside formerv has I been mounted soras to permit ittobecarried along with the inside former by force transmitted through the work clamped between the formers; I believe. it to be undesirable to rely upon the outside formers being ad vanced :to' or F retracted from the flange-turn ing means'merely as a result of the hold of the formers upon the material OftllG upper.

Ari object of'the presentxinvention is therefore to improve upper molding, lasting and other 1 upper shaping machines by providing means which; not only" permit the outside formers; topmove 'vvith the inside former as work; Thissinvention is herein shown for illustrativepurposes. as applied to the-upper A molding;machineswhich are-shown and described in: BrockyUnited States Letters Patent NOS.1'.1;197;4;37Ha;I1d "1,197440-, granted S'eiptember15,:1 916; and which zforin in"- j turned sole attachingtflange onxthe heelpart if otramupper, huti it is to be 1 understood-that Specification of Letters Patent.

Application filed January 14; 1916. Serial No. 72,082.

theinvention is likewise applicable to lasting machines,and also to molding machines which formv an outturned sole attaching flange as shown for example in. Brock United StatesLetters Patent No. 1,160,135, granted Nov. 16, 1915'. A feature of the present invention resides in the combination with inside and outside formers and flange forming wipers, of means for insuring the elevation of one of said formers when the otherone is raised to compress the flange against the wipers. According to the illustrated embodiment of the invention the outside and inside formers are positively moved together in the advance or retraction of the formers with relation to the wiping means after the wiping operation;

The motion of the outside forming means mayadvantageously be derived from the moving inside former by appropriate me chanical connections between them. A "convenient construction for securing this end is shown by wayoteXample-in the accompanying drawings inwhich parts of a ma? chine of the kind described in the specification of Brock United States LettersPatent No: 1,197,437, granted Sept. 5,1916, are illustrated. y

Figure 1 of the drawingsis a side elevation of so much of that, machine with this invention applied to itas is necessary for illustrating this'invention.

Fig. 2 is a perspective, view Showingthe new features. A

Fig. 3 is a plan view, partly in section, showing the connections of the formers to their operating "elements. r I

The inside, formerl is mounted upon a rod 2 adaptedto be reciprocated in the post. 3 by suitable mechanism. ,At'tached to the rod 2 and projecting through an opening in the post/3 is a yoke 4- bearir'ig two rods 5 and 5. Thesefrods a'rerigidly connected to members 'ii (one only of which is shown) having flanges enteringfslots in the outside The flanges of the members 6 may be of such width and the slots in the outside formers of such depth as to allow sufiicient margln of overlap between the flanges and slot walls to maintain the flanges of members 6 1n overlapping lifting relation to the outside formers in the closed position of said formers relatively to inside formers varying somewhat in transverse dimensions.

In operation a completed upper is passed over the former 1 as usual and drafted for wardly about the same. Then the machine is treadled and the former is drawn into the machine by connection from bar 15 with the power mechanism, not shown. When the former with the upper surrounding it has become seated backwardly against the outside formers the latter are closed around the inside former by connection from rod 16 to the power mechanism and thereafter the wipers 18 are advanced and closed by rod 20 over the tread face of former 1 to shape the heel seat flange. Next it is neces sary to crush down the flange and compress it between the wipers and former 1 and for this purpose the former carrying rod 2, which is nowover a plunger connected with toggle 25, is elevated by straightening of the toggle through its connection with the power mechanism. In such elevation of rod 2 and the inside former 1, the outside formers are compelled to participate fully and unvaryingly by reason of the motion of yoke l, rods 5, 5 and members 6. The loose connections of the outside formers with their operatin members 10 permit them to rise without isturbing the operating mechanism. On the completion of the molding operation,

' the rod 2 retires and the reverse operations take place.

By operating in such a way the compression of the flange after the wiping operation can be secured without straining the upper in such a way as to result in damage thereto. i This invention is also applicable to heel lasting machines, in the use of which it is customary to force the last upwardly against the wipers to crush the flange down upon the innersole'and it is desirable that the heel band, which corresponds to outside formers, shall be elevatedwith the last.

Having explainedthe nature of this invention and described an illustrative construction embodying the same, I claim as new and desire to secure United States 1. In a machine formolding the heel ends by Letters Patent 01" the ,of uppers for the purpose indicated, the
